Denver, the train was known as the Denver Zephyr, but on to Oakland was
the California Zephyr until July 11, 1971, ?? until November, City of
San Francisco from November 14, 1971, and San Francisco Zephyr from
June 11, 1972. The Denver Zephyr name lingered until October 26, 1973, even
though the train began daily operation to Oakland in summer from June 11,
1972 to September 10, 1972, and year-around from June 10, 1973. The train became
the California Zephyr once again on the reroute via Grand Junction
in 1983, after the introduction of Superliners in 1980.
